Abstract: An improved programming interface which provides for event scheduling, improved variable declarations allowing for configuration of declaration parameters, and improved handling of I/O objects. In modern day computing devices and especially in networks of such devices it is important to provide for event scheduling; known computing devices allow for event scheduling based on the occurrence of a predefined event. However, such a system present shortfalls in that flexibility is not provided to allow scheduling based on any arbitrary condition. Therefore, it is disclosed to provide a programming environment which allows for event scheduling where the event may be any arbitrary condition thus providing increased flexibility in event driven programs. In addition, programs which run on such computing devices typically declare one or more variables; such variables having one or more parameters associated therewith.
